To save $5 go to your local office and ask for a splitter. They'll
probably give you one. Bring in your payment at the same time to feel
like less of a tool.

Specifically, or at least in brooklyn park MN  if you get one of the
SD small motorola boxes it won't have serial but the older big ones
do. They usually have both at the office. Of course the newer ones are
smaller and faster, but they are also uglier and have no serial. The
HD boxes all have firewire (which you can use to change the channel)
but I haven't seen one with serial. They also have a 1/8 headphone
jack style IR port but I have no idea if that's in or out or even if
its operational at all.. anyone else know?
